This paper provides a historical review of the literature on effects radiation-induced displacement damage in semiconductor materials and devices. Emphasis is placed technologically important bulk silicon The primary goals are to provide guide literature, offer critical comments regarding that an attempt identify key findings, describe how understanding mechanisms has evolved, note current trends. Selected tutorial elements included as aid presenting information more clearly frame reference...
Chronic work-related stress is an independent risk factor for cardiometabolic diseases and associated mortality, particularly when compounded by a sedentary work environment. The purpose of this study was to determine if office worksite-based hatha yoga program could improve physiological stress, evaluated via heart rate variability (HRV), health-related outcomes in cohort workers. Thirty-seven adults employed university-based positions were randomized upon the completion baseline testing...
Background Chronic low back pain is a worldwide burden that not being abated with our current knowledge and treatment of the condition. The fear-avoidance model used to explain relationship between disability in patients chronic pain. However there are gaps empirical support for pathways proposed within this model, no evidence exists as whether physical activity moderates these pathways. Methods This was cross-sectional study 218 people Multiple mediation analyses were conducted determine...
Correlation is made between the effects of displacement damage caused in several types silicon bipolar transistors by protons, deuterons, helium ions, and 1 MeV equivalent neutrons. These measurements are compared to calculations nonionizing energy deposition as a function particle type energy. Measurements were factors for 2N2222A 2N2907A switching transistors, 2N3055, 2N6678, 2N6547 power collector current using 3.7 - 175 4.3 37 16.8 65 ions. Long term ionization on value taken into...
<para xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> Experimental results are presented on single-bit-upsets (SBU) and multiple-bit-upsets (MBU) a 45 nm SOI SRAM. The accelerated testing show the SBU-per-bit cross section is relatively constant with technology scaling but MBU increasing. data importance of acquiring analyzing respect to location multiple-bit upsets since relative cells important in determining which can be corrected error...
Experimental results are presented on proton induced single-event-upsets (SEU) a 65 nm silicon-on-insulator (SOI) SRAM. The low energy SEU very different for the SRAM as compared with SRAMs fabricated in previous technology generations. Specifically, no upset threshold is observed decreased down to 1 MeV; and sharp rise cross-section below MeV. increase MeV attributed upsets caused by direct ionization from protons. implications of discussed space applications SRAMs; radiation assurance...
Basic mechanisms and ground-test data for radiation effects in solid-state imagers are reviewed, with a special emphasis on proton-induced silicon charge-coupled devices (CCDs). For the proton fluxes encountered space environment, both transient ionization displacement damage arise from single-particle interactions. In former case, individual tracks will be seen; latter, dark-current spikes (or hot pixels) trapping states that cause degradation charge-transfer efficiency observed....
This study compared acute (15 min) yoga posture and guided meditation practice, performed seated in a typical office workspace, on physiological psychological markers of stress.

To examine changes in hamstring muscle fatigue and central motor output during a 90-minute simulated soccer match, the concomitant maximal torque rate of development.Eight amateur male players performed with measures at start every 15-minutes each half. Maximal (Nm) development (RTD; Nm.s-1) were calculated from isometric knee flexor contractions 10° flexion. Hamstring peripheral was assessed size shape resting twitch (RT). quantified voluntary activation (%) normalized biceps femoris (BF)...
The primary aim of this study was to evaluate the benefits resistance training (RT) on quality life (QOL) and fatigue in breast cancer survivors as an adjunct usual care. We recruited 39 women who had survived [mean age (y) 51.9 ± 8.8; time since diagnosis (m) 11.6 13.2]. Primary outcomes were assessed by Functional Assessment Chronic Illness Therapy – Fatigue (FACIT) scale QOL Cancer General (FACT-G) scale. ANCOVA used assess change while controlling for baseline values, with effect sizes...
We examined the effects of a 12-week program Nordic hamstring exercises (NHE), administered before or after football training, upon eccentric strength, muscle activity, and architectural adaptations. Amateur soccer players were randomized into three groups. The control group (CON; n=11) undertook core stability exercises, whereas periodized NHE was delivered either (NHEBEF ; n=10) (NHEAFT n=14) biweekly training sessions. Outcome measures included peak torque concomitant normalized surface...
Low- and high-energy proton experimental data error rate predictions are presented for many bulk Si SOI circuits from the 20-90 nm technology nodes to quantify how much low-energy protons (LEPs) can contribute total on-orbit single-event upset (SEU) rate. Every effort was made predict LEP rates that conservatively high; even secondary generated in spacecraft shielding have been included analysis. Across all environments investigated, when operating within 10% of nominal voltage, LEPs were...
The primary purpose of this study was to investigate whether a single session spinal manipulation (SM) increases strength and cortical drive in the lower limb (soleus muscle) elite Taekwondo athletes. Soleus-evoked V-waves, H-reflex maximum voluntary contraction (MVC) plantar flexors were recorded from 11 athletes using randomized controlled crossover design. Interventions either SM or passive movement control. Outcomes assessed at pre-intervention three post-intervention time periods...
